I bought this Usb wifi adapter from Xaomi on https://www.aliexpress.com

When I connected into PC with Windows OS in device manager, I have this.

So I google it and find out, that I had to use SW from MiWifi.com. I tryed to install it, but this SW is only in Chinese language and it looks very strange. I do not like it. I found working drivers for Windows7 x64.

And that’s it. Now you go to Network and Sharing Center and connect to any wirelles network without any other SW.

Drivers for Xaomi wifi adapter you can download here.
